The history of electronics, in Electronics




The third and final trade magazine that I saved is the April 17, 1980 Commemorative Issue of Electronics.  This issue traces the history of electronics from it's start through the end of the 1970's.  I thumbed through the issue and scanned a small set of the photos for your enjoyment.

Through the 1970's, many small-quantity systems were built using wire-wrap.  At Ford, we had a standard board set.  Engineers would lay out the sockets and components for their designs and annotate their circuit diagrams with the matrix locations of the components and pin numbers.  A tech would code these and they would be entered onto a punch card deck.  This was then read into a computer-driven wire wrap machine that would position a gun for a wire-wrap technician.  Modifications were made manually and, once a board was debugged, the card deck was updated.
